【発明の詳細な説明】 腫」 補助バンド付伸張フィルム 及五五１１ 本発明は、荷台や類似の物体を包むためのもの、特に比較的細い補助バンドをラ ミネートさせた伸張フィルムに関するものであり、本発明は更に伸張フィルム製 造にも関する。[Detailed description of the invention] 'tumor' Stretch film with auxiliary band 5511 The present invention is particularly useful for wrapping relatively thin auxiliary bands for wrapping carriers and similar objects. The present invention also relates to a laminated stretch film. It also relates to construction.

今日、様々な伸張フィルムが種々の製品や他の商品を包むために利用されている 。伸張フィルムの主要な使用法の一つは山積みにされた箱の荷台や類似物を包む ことである。この包装の過程において、コンテナ上の一台の荷台はかなり幅のあ る伸張フィルムを数回捲き付けて包むようにするが、そうするための様々な方法 が知られている。使用される伸張フィルムは、かなり伸び性が良く、荷台のまわ りに捲き付ける際に、フィルムを適度な引張力の下に維持すると、フィルムは角 部は他の不規則な形に従って変形するだけでなく、コンテナを互い同志、かつ荷 台上でしっかりと保持するだけの引張力を維持するようになる。しかしながら、 鋭い角部や、同様のものに伸張フィルムを捲き付けると、フィルムが裂けてしま うことがあり、これを避けるため、特にそのような各部に捲き付けるときには、 フィルムにかける引張力に十分な配慮がなされなければならない、また、一般に 伸張フィルムは透明で何も書かれていないが、このフィルム上に印刷するのは困 難であるか、または不可能である。またたとえ、印刷が可能であっても、この印 刷工程は伸張フィルムの価格をおよそ２倍にしてしまう。Today, various stretch films are used to wrap various products and other goods. . One of the major uses of stretch film is wrapping stacked box carriers and similar That's true. During this packaging process, one loading platform on the container is quite wide. There are various ways to wrap the stretch film by wrapping it several times. It has been known. The stretch film used has quite good stretchability and can be used around the loading platform. If you keep the film under moderate tension when wrapping it around the The parts not only deform according to other irregular shapes, but also move the containers towards each other and the load. It will maintain enough tension to hold it firmly on the table. however, Wrapping stretch film around sharp corners or similar objects will cause the film to tear. To avoid this, especially when wrapping such parts, Careful consideration must be given to the tensile force applied to the film, and in general Stretched film is transparent and has nothing written on it, but it is difficult to print on this film. difficult or impossible. Also, even if printing is possible, the The printing process approximately doubles the price of stretched film.

シェラ−（Ｓｃｈｅｌ　１ｅｒ）による米国特許４．４９９．７０６号は、角部 でフィルムが裂けるという問題に気づいており、そのような裂けを防止するため に、コンテナの角部と最も出会いそうな位置で、フィルムの余分の層を設けるた めに、フィルムの端で寄せ集められたフィルムチューブを備えている。この裂は 防止をするためには、更に厚みのあるフィルムを使用することもできるが、これ は必然的にコストを上昇させ、また望ましい程度の伸びを生じさせるのに必要な 引張力を増大させる結果になってしまう。U.S. Pat. No. 4,499,706 to Scheler et al. We are aware of the problem of film tearing and to prevent such tearing. to provide an extra layer of film where it is most likely to meet the corners of the container. It has a film tube that is gathered together at the edge of the film. This crack is To prevent this, it is possible to use a thicker film, but this will inevitably increase costs and increase the amount necessary to generate the desired amount of growth. This results in an increase in tensile force.

本願出願人は帯状フィルムからなる補助バンドを付は加えた標準の厚さの伸張フ ィルムを提供することにより、重いゲージ即ちラミネートフィルムの利点を得る ということがわかった。The applicant has developed a standard thickness stretch film with an auxiliary band made of strip film. Gain the benefits of heavy gauge or laminate film by providing film That's what I found out.

この補助バンドは伸張フィルムと同型の素材および同じ厚さの素材であってもよ いし、あるいは伸張フィルムとは異なるゲージまたは異なる素材でもよい。その 上、商品や荷主を確認したり、他の目標的を確認するために、着色や印刷された 目印といった目に見える特徴を補助バンドに持たせることができる。本発明の経 済的な利点は補助バンドに印刷をした時に、特に意味をもつ、なぜならば、単に 一本のフィルムロール上に連続印刷をして、多数の補助バンドに切断した後に、 何も印刷していない伸張フィルム上に補助バンドをラミネートすることができる からである。This auxiliary band may be of the same type and thickness as the stretch film. Alternatively, it may be a different gauge or a different material than the stretch film. the on the top, colored or printed to identify the product or shipper, or to identify other targets. The auxiliary band can have visible features such as landmarks. The history of the invention The economical advantages are particularly significant when printing on the auxiliary band, since it is possible to simply After continuous printing on one film roll and cutting into many auxiliary bands, Auxiliary bands can be laminated onto unprinted stretch film It is from.

ましい　１の弓日 本発明によれば、一定のゲージおよび厚さの伸張フィルム上に、通常より幅の狭 い補助バンドを積層させてラミネートをつくり、荷台や類似の物を包むのに用い ることができる。ここでいう「積層する」とは層と層の間に何らかの粘着性が生 じるように一つの層を他の層に対して置くことを意味する。素材は十分な粘着性 を有しているので、接着剤あるいは類似のものは必要としない、しかし、現在の ところ補助バンド素材の少な（とも一方の側を、無色、無性の液体である、比重 が０．８７１から０、８８７のイソブチレンの在いフィルムでコーティング処理 するのが望ましい、そうすることにより、眉と層を一緒にしておいて、１５．５ °ＣでＡＳＴＭ試験Ｄ試験２９８法で測定した時、強い粘着効果を生じることが 確認された。その他の粘着性のある物質、即ち粘着材も使用することができ、こ れらについては下記の特許請求の範囲中で「粘着剤」として集合的に述べる。Beautiful 1st bow day According to the present invention, a narrower than usual width is A laminate is made by stacking a number of secondary bands and is used to wrap cargo platforms and similar items. can be done. "Laminating" here means that there is some kind of adhesiveness between the layers. means to place one layer against another so that it is The material is sticky enough does not require adhesive or similar, but the current However, the auxiliary band material is small (and one side is a colorless, asexual liquid, with a specific gravity Coated with isobutylene-containing film with 0.871 to 0.887 It is desirable to do this, so that the eyebrows and layers are kept together, 15.5 Can produce a strong adhesive effect as measured by ASTM Test D Test 298 at °C. confirmed. Other sticky substances, i.e. adhesives, can also be used; These are collectively referred to as "adhesives" in the claims below.

一方、補助バンドは巻き取られたときに、基材の幅を適度に横切るようにしであ るので、バンドの厚みは巻き取り−ルの幅の上に均一に分散される結果、巻き取 り外直径の一部分が大きくなるようなことはない。On the other hand, the auxiliary band should cross the width of the base material appropriately when rolled up. As a result, the thickness of the band is evenly distributed over the width of the winding wheel. There is no possibility that a portion of the outer diameter will become larger.

本発明は伸張フィルムと補助バンドの素材の多くの組合わせで実行することがで き、製品の予想される使用法により、その選択ができる。以下の次側は本発明の 現在好ましい実例を示している。The invention can be implemented with many combinations of stretch film and auxiliary band materials. The choice depends on the expected use of the product. The following is the invention A currently preferred example is presented.

火皿ニ 一台の木製荷台に４フイートの高さまで、積荷用段ボール箱が積み上げられてい る。荷台とボール箱は、直線状（ｌｉｎｅａｒ）低密度ポリエチレン６０ゲージ 伸張フイルムを４回重ねて包んだ。使用中、伸張フィルムは１００％の伸び率を 生じるのに十分な引張力が与えられた。取扱い中に発生しつるような裂けを想定 して、包装の下端面近くで小さなナイフを用いて切り裂きをした。裂けはこの切 口のところから始まり、速やかに包装の幅を横切って伝わり、もとの包装状態を 破壊した。hot dish Cardboard boxes for cargo are stacked up to 4 feet high on a single wooden platform. Ru. The loading platform and cardboard box are made of linear low-density polyethylene 60 gauge. It was wrapped with stretched film 4 times. During use, the stretched film has a 100% elongation rate. Sufficient tensile force was applied to cause Assuming vine-like tears that occur during handling. Then, a small knife was used to cut the package near the bottom edge. The tear is this cut. It starts at the mouth and quickly travels across the width of the package, leaving behind the original package. Destroyed.

夾豊ス フィルムの包装は実例１の荷台及び段ボール箱から取り除かれた。２インチ幅の ８０ゲージポリエチレンフイルムの補強バンドがラミネートされた実例１と同様 の伸張フィルムで、荷台と段ボール箱のまわりを実例１と同様な方法で包んだ。Kyohosu The film packaging was removed from the carrier and cardboard box of Example 1. 2 inch wide Same as Example 1 with laminated reinforcing band of 80 gauge polyethylene film. The loading platform and cardboard box were wrapped with stretch film in the same manner as in Example 1.

引張力は実例１と同程度の伸び率を生じるに十分なように維持された。伸張フィ ルムを切裂いたとき、最初、裂けは包装の幅を横切るように走るが、補強バンド のところで止まったので、補助バンドの効果が実証された。The tensile force was maintained sufficient to produce elongation rates similar to Example 1. extension fi When the package is torn, the tear initially runs across the width of the package, but the reinforcing band The effect of the auxiliary band was demonstrated as it stopped at .

夫■ユ ３０インチ幅の鮮紅色の１００ゲージポリエチレン素材を１インチ幅に切断して 補助バンドのフィルムロールにした。この補助バンドを素材が透明の２０インチ 幅の６０ゲージポリエチレンフイルム中に再び捲き込んで補助バンド付伸張フィ ルムを得た。この伸張フィルムを用いて実例１の耐裂性試験を受けたとき、実例 ２における結果と同様の結果が記録された。さらに補助バンドは透明な伸張フィ ルムを通して明らかに識別できるので、荷台の荷は他と容易に区別できた。Husband Yu Cut 30 inch wide bright red 100 gauge polyethylene material into 1 inch width. I made it into a film roll for the auxiliary band. This auxiliary band is made of transparent material and is 20 inches long. Wrap it again in a wide 60 gauge polyethylene film and attach a stretch film with an auxiliary band. Got Lum. When this stretched film was subjected to the tear resistance test of Example 1, Results similar to those in 2 were recorded. In addition, the auxiliary band has a transparent stretchable filament. The load on the carrier was easily distinguishable from the others as it was clearly visible through the lume.

夫Ｌ４ 印刷可能なように表面を特別に処理した３０インチ幅の１００ゲージポリエチレ ンのフィルムロールに荷主を確認するスイス文字を肉太活字で相等しい１５行間 隔に印刷した。印刷の方向は、使用時にそれの配置の方向が問題にならないよう にするため、周期的に逆にした。このフィルムロールはその後２インチ幅の補助 バンドである１５本のフィルムロールに切断され、各フィルムロールは実例１と 同一の２０インチ幅の伸張フィルムロールにラミネートされた。Husband L4 30 inch wide 100 gauge polyethylene with specially treated surface for printability 15 equal lines of Swiss letters in bold type identifying the shipper on each film roll. printed in intervals. The direction of the print is such that the direction of its placement does not matter when in use. I reversed it periodically to make it. This film roll is then 2 inch wide auxiliary The band is cut into 15 film rolls, each film roll is as shown in Example 1. It was laminated to the same 20 inch wide stretch film roll.

フィルムが１００％引き伸ばされて、もとの長さの２倍にまで引き伸ばされた場 合でも、印刷文字は最終製品の中において、遠方から容易に認識することができ た。If the film is stretched 100% and stretched to twice its original length. Printed characters can be easily recognized from a distance in the final product, even if Ta.

火皿１ １００ゲージポリエチレンフイルムのロールに長方形の模様を印刷した。各長方 形はその長さのおよそ２倍の横幅をフィルムの幅に沿って有していた。このフィ ルムロールは前例と同じように幅の狭いフィルムロールに切断し、実例１で使用 した型のポリエチレン製の伸張フィルムロール中に再び捲き込んでラミネートフ ィルムを得た。このラミネートフィルムは前と同じ様に、荷台の積荷を包むため 引き伸ばして使用され、引き伸ばされたとき、バンド上の長方形は縦に大きくな り、横方向に縮んだ。この長方形の変形により伸張フィルムを使用している人は 、伸びの量の推量が正確にできた。Fire plate 1 A rectangular pattern was printed on a roll of 100 gauge polyethylene film. each rectangle The shape had a width along the width of the film approximately twice its length. This fi The roll is cut into narrow film rolls as in the previous example and used in Example 1. Roll it up again into the same type of polyethylene stretch film roll and laminate it. I got a film. As before, this laminated film is used to wrap the cargo in the cargo bed. When used stretched, the rectangle on the band becomes larger vertically. and shrunk laterally. Due to this rectangular deformation, people using stretch film , the amount of elongation could be accurately estimated.

実例３．４及び５においては、幅の狭い補助バンドは目で見て区別できるので、 作業者は包装工程の初めにリール上に捲かれているリール上の伸張フィルムの端 を容易に探し出せた。In Examples 3.4 and 5, the narrow auxiliary band is visually distinguishable, so At the beginning of the packaging process, the operator checks the edge of the stretch film on the reel as it is wound onto the reel. was easy to find.

前述の例は、決して本発明の適用のすべてを表わしたものではない、ポリプロピ レン、ポリ塩化ビニール、ポリウレタンを含む他の様々な包装素材のどれでもが 補助バンドとして使用できるし、同様にポリエチレン以外の′素材を基材として 使用できる０例では、予め捲かれたフィルムが一緒に再び捲き込まれたが、バン ドの１つないし２つをフィルム押出様の外で、他の表面上にラミネートしてもよ い。The foregoing examples are by no means representative of all applications of the invention; Any of a variety of other packaging materials including polyurethane, polyvinyl chloride, and polyurethane It can be used as an auxiliary band, and it can also be used as a base material other than polyethylene. In the zero cases available, the pre-wound film was re-wound together, but the band One or two of the boards may be laminated outside the film extrusion onto other surfaces. stomach.

本発明は、細部において様々な修正や変更をすることができるので、前述のもの は発明の例として解釈されるべきである。Since the present invention is susceptible to various modifications and changes in details, should be construed as an example of an invention.
